The clay core of bronze sculptures made by lost wax casting can also be tested. The exposure to radioactive elements continues, and the minerals begin again storing free electrons in their structures. Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired. Depending on the depth of the traps the storage time of trapped electrons will vary - some traps are sufficiently deep to store charge for hundreds of thousands of years.

Luminescence Dating

When a specimen is reheated, the trapped energy is released in the form of light thermoluminescence as the electrons escape. Electrons from these substances get trapped in the mineral's crystalline structure, and continuing exposure of the rocks to these elements over time leads to predictable increases in the number of electrons caught in the matrices. Thermoluminescence dating Thermoluminescence TL dating is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated lavaceramics or exposed to sunlight sediments. Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired. The term luminescence refers to the energy emitted as light from minerals such as quartz and feldspar after they've been exposed to an ionizing radiation of some sort. Es, chronology, keywords:
